About this study

Official title: Phase 1/2, Open Label & Double Blind Randomized Placebo-controlled Study to Assess the Feasibility of BGC101 (EnEPC) in the Treatment of Peripheral Arterial Disease (PAD) With Critical Limb Ischemia (CLI)

Evaluate the feasibility of an autologous cell preparation composed of a mixture of cells enriched for endothelial progenitor cells (EnEPCs) and multipotent adult hematopoietic stem/progenitor cells (HSPC) (BGC101), in the treatment of patients suffering from peripheral arterial disease (PAD) with critical limb ischemia (CLI) who have not responded to optimal pharmacological treatment or control of risk factors and/or had a revascularization failure, and do not have the option of further revascularization treatment.

Read the detailed description

BGC101 is designed to treat peripheral vascular disease in patients suffering from Critical Leg Ischemia (CLI) also referred to as chronic limb threatening ischemia (CLTI).

This part of the study is designed as a placebo double-blind randomized controlled trial (CRT) assessing the safety and efficacy of BGC101 in 45 eligible subjects in 2 Arms: Arm A: BGC101 treatment and Arm B: Placebo treatment. The Arm A:Arm B ratio is 2:1 A single dose treatment of the personalized cells by intramuscular injections into the affected leg takes less than 10 minutes.

Cells from a standard blood draw (with no pre-treatment, bone marrow aspiration, mobilization or apheresis) are transformed, within a day, into the investigational medicinal product BGC101.

BGC101, intended for autologous use, is a 'ready-to-use' cell suspension in prefilled syringes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety (Incidence of adverse events)

    • Incidence and proportion of incidence between treatment arms of adverse events of specific interest (AESI) and injection-related AE
    • Incidence of serious adverse events (SAEs) including SAEs related or probably related to the treatment
    • Vital signs, physical examination, and electrocardiogram (ECG)
    • Safety laboratory values of hematology, blood chemistry, and urinalysis
    • Local tolerability (injection site reaction)

    Measured: 12 Months

  2. Efficacy (Improvement of indication signs)

    • Major amputation (below or above the knee) rate at Month 12
    • Major amputation-free survival (AFS) rate at Month 12

    Measured: 12 Months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing BGC101 (autologous EnEPC preparation) in people with Chronic Limb-Threatening Ischemia and Peripheral Arterial Disease, run by BioGenCell Ltd. at 5 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 18 inclusion and 29 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 6 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States, Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety (Incidence of adverse events) (time frame: 12 Months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02805023, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Jun 2025.
